Step 1: Prepare the Oven and Pan: Preheat oven to 350F (175C). Grease and flour a 9-inch round cake pan or a 9x13 inch baking pan. Ensuring the pan is properly prepared prevents the cake from sticking, allowing for easy removal and a beautiful presentation.
Step 2: Combine Wet Ingredients: In a large mixing bowl, combine the melted butter, milk, eggs, vanilla extract, and almond extract (if using). Whisk until well blended. This mixture forms the moist base of the cake, providing richness and flavor.
Step 3: Incorporate Cake Mix: Add the yellow cake mix to the wet ingredients. Using an electric mixer, blend on low speed until just combined. Be careful not to overmix, as this can result in a tough cake. A few lumps are acceptable at this stage.
Step 4: Arrange Peach Slices: Pour the cake batter into the prepared pan, spreading it evenly. Arrange the sliced peaches on top of the batter in a decorative pattern. Press the peach slices gently into the batter. This adds a burst of juicy flavor and creates a visually appealing topping.
Step 5: Add Optional Topping: If desired, mix together the granulated sugar and ground cinnamon. Sprinkle evenly over the peach slices. This creates a caramelized, slightly crunchy topping that enhances the cake's sweetness and adds a hint of spice.
Step 6: Bake the Cake: Bake in the preheated oven for 35-40 minutes, or until a wooden skewer inserted into the center comes out clean. The cake should be golden brown on top and spring back lightly when touched.
Step 7: Cool and Serve: Let the cake cool in the pan for 10-15 minutes before inverting it onto a wire rack to cool completely. Dust with powdered sugar before serving. Enjoy this warm or at room temperature.
Optional Tips: For a richer flavor, substitute melted butter with coconut oil. For a tangier taste, substitute half the milk with sour cream or Greek yogurt. The recipe can be adapted using other fruits like nectarines or plums. For extra crunch, sprinkle chopped nuts (almonds, pecans) over the peaches before baking.
